The PC1 has a bit of a reputation, not sure why. I've used them, only with a dead straight chain line mind, but what I didn't like was how it suddenly 'stretched' after a period of being good. I've since gone to heavier, track chains and they aren't giving me any issue at all (thank heavens, they can be pricey). Get a good chain and it's not changed often enough for price to be an issue, especially if you use more than one bike (ie, not one chain copping all the abuse).
